Has anyone replaced their 12V battery with lithium?

Mon May 18, 2020 2:59 pm

I saw a video on YouTube of a guy who replaced his 12 lead acid accessory battery for his Fiat 500e electric vehicle and he's not had any issues for at least 2 years. I would like to do this too with my 2016 Kia Soul EV+. Does anyone have any experience with this and if so, what battery did they use? The guy in the video used the ReLion RB20 (20ah LiFEPO4) lithium ion battery.

Here's the battery: https://www.ecodirect.com/RELiON-RB20-1 ... J0QAvD_BwE

And here's the YouTube video: https://youtu.be/X_0lFn9YFNg

Is there anything I need to watch out for before doing this? These batteries are supposed to last several times longer than lead acid batteries and have several other advantages too. Any thoughts?

Thanks!

Quote from the Kia Service Manual:

"When replacing the battery, it should be same one (type, capacity and brand) that is originally installed on your vehicle. If a
battery of a different type is replaced, the battery sensor may recognize the battery to be abnormal."

Same brand? That's interesting. The one in there now is from Hyundai's battery division. Might be hard to come by! But anyway, it shouldn't be detected as abnormal because it supplies the same power profile. In fact it's better than the included vehicle battery in pretty much every category (but you wouldn't want to use it in an ICE application because it's not designed for supplying cranking amps for a starter).

I got the battery yesterday. Smaller than I thought it would be, and only weighs about 6 pounds. The battery that's in the vehicle now looks like it's in excellent condition, so I will keep this one on hand just in case. I'm also looking through the warranty book to see if it would void the warranty.
